Claims (1)

[Claims for Utility Model Registration] (1) A plurality of vanes that can move forward and backward in the radial direction are installed in a cylinder chamber defined by a cylindrical cylinder and front and rear side blocks attached to both sides of the cylinder. A gas compressor in which a rotor having a refrigerant gas is rotatably horizontally mounted, and in which refrigerant gas is introduced into a cylinder chamber through a gas suction port and a suction passage formed in the front side block and the cylinder. By providing notches leading to the cylinder opening at both ends of the gas suction passage, and by forming the suction port of the front side block to communicate with the cylinder chamber and the suction passage, there is no direct flow from the suction port of the front side block into the cylinder chamber. A gas compressor characterized by introducing refrigerant gas and supplying the refrigerant gas into a cylinder chamber from a notch in the suction passage. (2) A concave portion is formed in the rear side block corresponding to the rear side notch of the refrigerant gas suction passage formed through the cylinder, thereby increasing the amount of refrigerant gas inflowing from the notch. A gas compressor according to claim 1 of the utility model registration claim.
